For example, safflower is extracted with water, the resulting water extract is evaporated to dryness in vacuum, and the residue is dissolved in a small amount of water. Furthermore, a method of precipitating calsamine yellow by adding an organic solvent that is immiscible with water (Japanese Patent Publication No. 53-394)

色素利用上の重大な課題であった。[Problems to be Solved by the Invention] However, the above-mentioned conventional extract containing yellow pigment obtained by water extraction of safflower or its concentrated solution generates precipitation over time.
When this was added to beverages, etc., it caused cloudiness and precipitation in the final product. In addition, even with yellow pigment-containing substances obtained by treating water extracts of safflower with organic solvents or activated carbon, it is often observed that similar turbidity or precipitation occurs over time when added to beverages, etc. This was a serious issue in the utilization of this dye.

濁又は沈澱の原因になるものと推定された。The present inventors have endeavored to investigate the cause of turbidity or precipitation caused by the safflower yellow pigment. As a result, it was found that alkaline earth metals such as calcium and magnesium contained in the safflower water extract caused turbidity or precipitation. It is assumed that these alkaline earth metals combine with acidic polysaccharides, proteins, peptides, etc. extracted with yellow pigment when extracting safflower with water to form insoluble substances, which cause turbidity or precipitation.

沈殿の原因となるものと推定された。Even with known methods, such as treating a safflower water extract with a water-soluble organic solvent or activated carbon, it is difficult to completely remove the acidic polysaccharides and peptides in the extract. It is estimated that this causes turbidity or precipitation. Furthermore, even if acidic polysaccharides and peptides are removed by these treatments, alkaline earth metal ions are not removed. Therefore, when the safflower yellow pigment obtained by the above treatments is added to beverages, such as fruit juice drinks, Since organic acids, amino acids, etc. are present in beverages, it is assumed that they form insoluble substances with alkaline earth metals, which causes turbidity or precipitation.

The inventors have discovered that these problems can be solved all at once, and have completed the present invention. Therefore, it is an object of the present invention to provide a safflower yellow pigment extract that does not form cloudiness or precipitate over time by the simple means of removing alkaline earth metals by treatment with an ion exchange resin.

Extraction was carried out by stirring at 70°C for 1 hour. After completion of the extraction, centrifugation was performed to separate the solid and liquid, and the resulting extract was heat sterilized at about 85° C. for 15 minutes, and then clarified by filtration with a filter paper coated with diatomaceous earth. This filtrate was then treated with cation exchange resin SK.
Ion exchange treatment was performed by passing the solution through a glass column with a diameter of 30 mm filled with 200 ml of 1B (Na+) (Mitsubishi Kasei) at an SV of about 2. The obtained treated solution was concentrated under reduced pressure, and Br
190 g of a safflower yellow pigment concentrate having a temperature of ix65° was obtained (Product 1 of the present invention). 1 g of this concentrated solution was diluted to 2000 ml using a pH 4.0 buffer solution, and the wavelength was 400 nm using a 1 cm cell.
The measured absorbance at m was 0.925. In addition, the amount of Ca measured by atomic absorption spectrometry is

トラブルの発生を完全に防止することができる。According to the present invention, by the simple means of treating a safflower yellow pigment extract with a known cation exchange resin, it is possible to impart stability over time to the pigment in an extremely industrially advantageous manner. That is, it is possible to almost completely prevent turbidity or precipitation during storage of the safflower yellow pigment extract concentrate itself or food and drink products to which the pigment has been added. Therefore, the safflower yellow pigment according to the present invention can be suitably incorporated into beverages such as transparent fruit juice drinks, transparent non-fruit juice drinks, sports drinks, medicinal drinks, tea drinks, and milk drinks. When added to ice cream, sherbet, Japanese/Western confectionery, and other food and drink products, it can completely prevent problems such as turbidity, color bleeding, and spotting.
